That's what I thought too. Herm also confirmed very little clearance needed.
Tonight I took the whole thing back apart measuring shaft stick out, bearing thickness, clearances etc. it turns out there is .028" of clearance or end play between the rev. Gear and rear bearing. Since its pinched between the bearing, which is bottomed on the step (verified) and the snap ring that holds the low/rev synchro hub in place there doesn't seem to be any way to reduce e clearance. Unless I add a thrust washer somewhere which concerns me greatly. Wouldn't Adding parts inside would seem just as bad as forgetting one ?. BTW the new gear thickness and old gear thickness are within .001"
Any other ideas before I put it back together. I'm actually leaning towards adding a thrust washer between the bearing and the rev. Gear as the best solution.
